Exclusive {rho}{rho} production in two-photon collisions is studied at LEP for quasi-real photons ({gamma}{gamma}, centre-of-mass energies 161 GeV {<=} {radical}(s) {<=} 209 GeV, total integrated luminosity L=698 pb-1) and one virtual photon ({gamma}{gamma}*, 89 GeV {<=} {radical}(s) 209 GeV, L=855 pb-1). The cross sections of the {rho}{rho} production processes are determined as a function of the photon virtuality, Q2, and the two-photon centre-of-mass energy, W{gamma}{gamma}, in the kinematic region: Q2 {<=} 30 GeV2 and 1 GeV {<=} W{gamma}{gamma} {<=} 3 GeV.
